How to use the slag of Incineration

With the acceleration of urbanization, the issue of garbage disposal is receiving increasing attention from people. Incineration is a common waste treatment method, but the resulting slag has become a problem. Improper disposal of slag will cause serious environmental pollution, so how to use the slag from Incineration has become an urgent problem.

1、 Composition of Incineration slag

Incineration slag refers to the solid waste generated during Incineration after high-temperature combustion due to the large amount of organic and inorganic substances contained in garbage. The composition of Incineration slag is complex, including inorganic salt, glass, metal, ceramics, etc.

2、 Hazards of Incineration slag

If the Incineration slag is not properly treated, it will cause great harm to the environment. First of all, Incineration slag contains a large number of heavy metals and harmful substances. If dumped directly on the land, it will pollute the soil and groundwater. Secondly, the organic and inorganic substances in the Incineration slag will remain in the slag. If not properly treated, it will affect the surrounding environment and human health.

III. Utilization of Incineration slag

In order to solve the environmental problems caused by Incineration slag, we need to find a suitable utilization method. At present, the utilization of Incineration slag mainly includes the following ways:

1. Landfill

Landfill is a common waste treatment method and also a treatment method of Incineration slag. Landfill Incineration slag underground can effectively reduce its impact on the environment. However, the drawbacks of landfilling are also obvious. Firstly, landfilling requires a large amount of land resources, and secondly, landfilling can cause pollution to the land and groundwater.

2. Cement products

The inorganic substances in Incineration slag can be used to make cement products. High strength cement products can be produced by mixing Incineration slag with cement. This method can effectively use Incineration slag and reduce the impact on the environment.

3. Road construction

Inorganic substances in Incineration slag can be used to build roads. High strength pavement materials can be made by mixing Incineration slag with asphalt. This method can effectively use Incineration slag and reduce the impact on the environment.

4. Agricultural use

Inorganic substances in Incineration slag can be used to improve soil. The Incineration slag can be mixed with Organic fertilizer to produce efficient soil conditioner. This method can effectively use Incineration slag, and can also increase crop production.

4、 Conclusion

The treatment of Incineration slag is a complex problem, which requires us to find a suitable utilization mode. Landfill, cement products, road construction, and agricultural use are currently common utilization methods. We need to comprehensively consider various factors and select an appropriate utilization mode to reduce the impact of Incineration slag on the environment.
